I am using this post as a way to document my brief plans for tomorrow’s Google Meet lecture with the LOA students as well as to park the links to the resources and tools that I intend to use for… Continue Reading
Students are often confused about the forces in drawing free-body diagrams, especially so when they have to consider the different parts of multiple bodies in motion. Two-Body Motion Let’s consider the case of a two-body problem, where, a force F is applied… Continue Reading
I created this post here to bookmark some useful tools for use during my upcoming JC1 lectures on Dynamics. This is a simulation for collisions that show the momenta before and after collisions. It requires registration after one visit. A… Continue Reading
Problems involving two bodies moving together usually involve asking for the magnitude of the force between the two. For example: A 1.0 kg and a 2.0 kg box are touching each other. A 12 N horizontal force is applied to… Continue Reading
In a recent class on Kinematics, I prepared a string of 4 pendulum balls, each separated about 20 cm apart and dropped them from a height. Before that, I got students to predict whether the intervals in time between drops… Continue Reading
Through this GeoGebra app, students can observe how the gradient of the displacement-time graph gives the instantaneous velocity and how the area under the velocity-time graph gives the change in displacement. In the GeoGebra app below, you will see a… Continue Reading
This GeoGebra app allows students to observe the difference between instantaneous and average velocity from a graphical perspective.
This GeoGebra app allows users to change the magnitude and direction of the force acting on an object, as well as the initial velocity. The change in kinetic energy is calculated along with the work done in the direction of… Continue Reading
The following GeoGebra app simulates the force vectors on an object in uniform vertical circular motion. A real world example of this would be the forces acting on a cabin in a ferris wheel.
This is a simulation that shows the vectors of forces acting on an object rolling in a vertical loop, assuming negligible friction. To complete the loop, the initial velocity must be sufficiently high so that contact between the object and… Continue Reading
